HACCP vs ISO 22000: Food Safety Standards Compared
HACCP (Hazard Analysis Critical Control Point) is a preventive food safety system that identifies, evaluates and controls hazards throughout food production. ISO 22000 is an internationally recognised food safety management system standard that incorporates HACCP principles within a broader management system framework. The key difference is scope: HACCP is a hazard-control methodology, while ISO 22000 is a certifiable management system covering food safety policy, communication, emergency preparedness and continual improvement. Organisations that require formal certification typically choose ISO 22000; those that need a practical hazard-control system often implement HACCP alone.

What Each Standard Covers
HACCP focuses exclusively on food safety hazards. It is a seven-principle system that identifies where hazards can occur in the production process and establishes control measures at Critical Control Points (CCPs). HACCP is hazard-specific and process-specific; it does not address organisational food safety policy, supplier management, traceability, or management system documentation beyond what is needed to support the CCPs.
ISO 22000 adopts a wider scope. It integrates the HACCP principles with the requirements of a management system based on the Plan-Do-Check-Act cycle. ISO 22000 covers food safety policy and objectives, internal and external communication, management review, resource management, operational planning and control, validation and verification of control measures, traceability, emergency preparedness, and continual improvement. It aligns with other ISO management system standards such as ISO 9001 and ISO 14001, making it suitable for organisations that already use integrated management systems.
The Seven HACCP Principles
HACCP is built on seven core principles that remain unchanged regardless of the industry or product. These principles form the hazard-control foundation that ISO 22000 also incorporates.
| Principle | Description | Example Application |
|---|---|---|
| 1. Hazard analysis | Identify all biological, chemical and physical hazards at each process step | Identifying salmonella risk in raw poultry handling |
| 2. Determine CCPs | Identify points where control is essential to prevent or eliminate a hazard | Cooking temperature as a CCP for pathogen elimination |
| 3. Establish critical limits | Set measurable boundaries that separate acceptable from unacceptable | Minimum internal cooking temperature of 74°C |
| 4. Establish monitoring procedures | Define how and when CCPs will be measured and recorded | Check cooking temperature every 30 minutes |
| 5. Establish corrective actions | Define steps when a critical limit is breached | Re-cook product if temperature is below 74°C |
| 6. Establish verification procedures | Confirm the HACCP system is working effectively | Weekly calibration of temperature probes |
| 7. Establish record-keeping | Document all hazards, CCPs, limits, monitoring and actions | Temperature logs, corrective action reports |
ISO 22000 Requirements
ISO 22000 combines management system requirements with HACCP principles and prerequisite programmes (PRPs). The standard is organised into ten clauses. Clauses 1 to 3 cover scope, normative references and terms and definitions. Clauses 4 to 10 contain the actionable requirements.
Clause 4 (Context of the Organisation) requires you to determine internal and external issues that affect food safety, identify interested parties and their requirements, and define the scope of the food safety management system (FSMS). Clause 5 (Leadership) requires top management to establish a food safety policy, assign roles and responsibilities, and ensure the FSMS is integrated into business processes. Clause 6 (Planning) covers risk-based thinking, food safety objectives and planning for changes. Clause 7 (Support) addresses resources, competence, awareness, communication and documented information. Clause 8 (Operation) is the largest clause and covers operational planning and control, PRPs, the traceability system, emergency preparedness, hazard control (including HACCP), verification and validation, and control of nonconformities. Clause 9 (Performance Evaluation) requires monitoring, measurement, analysis, internal audit and management review. Clause 10 (Improvement) addresses nonconformity and corrective action, and continual improvement.
HACCP vs ISO 22000: Side-by-Side Comparison
| Dimension | HACCP | ISO 22000 |
|---|---|---|
| Nature | Hazard-control methodology | Certifiable management system standard |
| Scope | Hazard identification and control at CCPs | FSMS including PRPs, HACCP, communication, traceability, continual improvement |
| Certification | Not certifiable (can be audited but no ISO certificate) | Certifiable by accredited certification bodies |
| Governance body | Codex Alimentarius (FAO/WHO) | ISO (International Organization for Standardization) |
| Documentation | HACCP plan, CCP logs, corrective action records | Full FSMS documentation: policy, procedures, records, HACCP plan, PRPs, internal audit reports |

Integration Benefits
Organisations that already operate a HACCP system are well positioned to upgrade to ISO 22000. The HACCP plan forms the core of the ISO 22000 operational requirements, and the seven HACCP principles map directly to Clause 8 of the standard. The additional requirements are management system elements that most organisations already have in place for quality, environmental or health and safety management.
Integrating HACCP into ISO 22000 delivers several benefits. First, it provides a single, auditable framework that satisfies regulatory HACCP requirements and delivers an internationally recognised certificate. Second, it reduces duplication by combining HACCP documentation with management system records under one document control system. Third, it adds continual improvement processes that HACCP alone does not provide, helping your food safety performance improve over time. Fourth, it enables integration with other ISO standards such as ISO 9001 (quality) and ISO 14001 (environment), reducing audit frequency and cost.
Which Standard Should Your Organisation Choose?
The choice depends on your regulatory obligations, customer requirements and organisational ambition.
| Situation | Recommended Approach | Rationale |
|---|---|---|
| Small bakery or restaurant | HACCP only | Regulatory compliance without management system overhead |
| Food manufacturer exporting to GCC | ISO 22000 | Certification required by buyers and regulators |
| Existing HACCP system, no certificate | Upgrade to ISO 22000 | Leverage existing HACCP plan, add management system for certification |
| Multiple ISO standards already in use | ISO 22000 (integrated) | Aligns with ISO management system structure (Annex SL) |
| Supplier to supermarkets or hotels | ISO 22000 or FSSC 22000 | Certification often a contractual requirement |
| Start-up food business | HACCP first, ISO 22000 later | Build hazard control first, add certification as you grow |
Implementation Timeline
A typical ISO 22000 implementation project follows a phased approach. The timeline assumes a mid-size food manufacturing facility and an organisation that already has basic HACCP knowledge in place.
Month 1 – Gap Analysis and Planning: Assess existing HACCP system against ISO 22000 requirements, identify gaps, create project plan and budget. Month 2 – Training and Awareness: Train the food safety team on ISO 22000 requirements, update HACCP training for all production staff. Month 3 – PRP Development: Document prerequisite programmes (cleaning, pest control, maintenance, waste management, supplier control). Month 4 – FSMS Documentation: Write the food safety policy, procedures, HACCP plan update, traceability system, emergency preparedness plan. Month 5 – Implementation: Roll out the FSMS across operations, train staff on new procedures, begin recording. Month 6 – Internal Audit: Conduct the first internal audit, identify nonconformities and implement corrective actions. Month 7 – Management Review: Hold the first management review meeting, assess FSMS performance, approve improvements. Month 8 – Certification Audit: Stage 1 (documentation review) and Stage 2 (implementation audit) with the certification body.
FAQ
Is HACCP a legal requirement?
In most countries, including GCC member states, HACCP is a legal requirement for food businesses. However, the law typically requires implementation of HACCP principles, not certification to a standard.
Can I get ISO 22000 certified without HACCP?
No. ISO 22000 requires the implementation of HACCP principles as part of Clause 8 (Operation). You must conduct a hazard analysis, determine CCPs and establish critical limits as part of the FSMS.
Which is more recognised: HACCP or ISO 22000?
HACCP is universally recognised as a food safety methodology and is referenced in food safety regulations worldwide. ISO 22000 adds certification value that many international buyers and regulators require. If your market demands a certificate, ISO 22000 is more recognised.
What is the difference between ISO 22000 and FSSC 22000?
FSSC 22000 is a certification scheme that uses ISO 22000 as its foundation and adds sector-specific PRP requirements (ISO/TS 22002 series) and additional scheme requirements. It is GFSI-recognised, whereas ISO 22000 alone is not GFSI-benchmarked.
Do I need to replace my HACCP system to implement ISO 22000?
No. ISO 22000 builds on your existing HACCP system. You only need to add the management system elements that HACCP does not cover, such as a food safety policy, communication procedures, management review and continual improvement.
How much does ISO 22000 certification cost in the GCC?
For a mid-size food manufacturer in the GCC, ISO 22000 certification costs between USD 8,000 and USD 20,000, depending on the certification body, scope and complexity of operations. Recertification surveillance audits cost approximately USD 3,000 to USD 7,000 per year.
